In the laboratory at PAO Koks, the thermal solution of G, GZh, and Zh coal in anthracene oil is investigated. The optimal solution conditions are determined, and the product quality is investigated. It proves possible to produce satisfactory materials for binder production directly from coal, without high-temperature coking.
Research on the production and properties of coal pitch is conducted in the laboratory at PAO Koks. One topic of interest is the distillation of coal tar to produce a broad tar and pitch fraction, whose quality is analyzed. It is possible to regulate the characteristics of pitch: its ash content and content of components insoluble in toluene (the α fraction) and components insoluble in quinoline (the...
